Diablo Immortal is a mobile action RPG set in the world of Sanctuary, where you can explore dungeons, slay demons, and loot epic items. The game has several currencies and resources that you can use to enhance your character and gear, but one of the most important ones is Diablo Immortal Platinum.

Platinum is a semi-premium currency that can be used for various purposes, such as:

Creating a Clan, which is a social group that can share resources, chat, and participate in clan activities. To create a Clan, you need to be level 30 and pay 3000 Platinum.
Extracting Skill Stones from Charms, which are items that can boost your skills. To extract a Skill Stone from a Charm, you need to visit the Charm Craftsman and pay 500 Platinum.
Purchasing Echo Crystals, which are needed to upgrade your gems above rank 5. You can buy Echo Crystals from the Crystal Merchant in Westmarch for 500 Platinum each.
Purchasing Legendary Crests, which are used to enhance your Rift runs and get better rewards. You can buy Legendary Crests from the Rift Merchant for 1600 Platinum each.
